Gaussian Elimination - CliffsNotes
www.cliffsnotes.com › gaussian-eliminationGaussian elimination proceeds by performing elementary row operations to produce zeros below the diagonal of the coefficient matrix to reduce it to echelon form. (Recall that a matrix A ′ = [ a ij ′] is in echelon form when a ij ′= 0 for i > j , any zero rows appear at the bottom of the matrix, and the first nonzero entry in any row is to ...
Gaussian elimination - Wikipedia
en.wikipedia.org › wiki › Gaussian_eliminationIn mathematics, Gaussian elimination, also known as row reduction, is an algorithm for solving systems of linear equations. It consists of a sequence of operations performed on the corresponding matrix of coefficients. This method can also be used to compute the rank of a matrix, the determinant of a square matrix, and the inverse of an ...
